How could I capture the console output into a variable when running a utility so I can filter the text?
Example: I am trying to capture the console output when I type
bitcoind so that I can filter out the rpcpassword and write it to a config file.
ubuntu@ip-172-31-3-49:~$ bitcoind Error: To use bitcoind, you must set a rpcpassword in the configuration file: /home/ubuntu/.bitcoin/bitcoin.conf It is recommended you use the following random password: rpcuser=bitcoinrpc rpcpassword=Eb5WDgzKqt77U4LhvvfnYxaNvw2rpztSvM5XKsonXBWC (you do not need to remember this password) The username and password MUST NOT be the same. If the file does not exist, create it with owner-readable-only file permissions. It is also recommended to set alertnotify so you are notified of problems; for example: alertnotify=echo %s | mail -s "Bitcoin Alert" firstname.lastname@example.org
